Mux / Demux Systems


DMD-P DarkStar Mux/Demux

Product Overview

The DMD-P is XKL’s DarkStar Mux/Demux product. As with the rest of the XKL product line, the DMD-P is based on XKL’s DarkStar architecture, the foundation for addressing today’s IT challenges and scalable growth.

The DMD-P is a passive device (i.e., not requiring power or cooling) that aggregates and provides monitoring capabilities for a mix of 1G through 400G technologies, resulting in greater control and scalability.

The DMD-P provides a variety of filter options including 48-channel or 96-channel Mux/Demux, or 4-band or 6-band filter, all of which allow for point-to-point or east/west configurations.

Offering the same optical filters as the DMD-A but without the DMDA’s amplification capabilities, the DMD-P device can serve as an integral part of an XKL network solution or can inter-operate with any optical networking equipment that utilize the standard ITU grid with 50GHz or 100GHz channel spacing.

The DMD-P is available in 1 rack unit (1U) or 2 rack unit (2U) configurations. Easy to integrate and operate, there is no need for specialized optical engineers to ensure network optimization.


  • Zero cost software updates.
  • No licensing fees.
  • Simplicity, reliability, durability.
  • Highly scalable solutions.
